' s'ras CHARLES H. HOWARD, OF SAU'GUS, MASSACHUSETTS, ASSIGNOR '10 PAPER PRODUCTS MACHINE COMPANY, OF BOSTON, -MASSACHUSETTS, A CORPORATION OF MASSA CHUSETTS.

' 5 hlassa'chusetts, have invented an Improvement in Paper-Reinforcing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to machines for reinforcing fabrics,

and more particularly to such machines for. reinforclng paper fabrics byv the application tion is an improvement upon the machine dlsclosed in myco-pending application, Serial Number 13l,259, filed December 1, 1916.

the said application, the reinforcing elements, which may be threads, cords, wires, orsimilar' filaments, are carried transversely of the machine or placed'in transverse relation to the .fabric to be reinforced. The means for carrying the filaments transversely may be in the form ofa series of grippers which move transversely of the machine and then the filaments are freed from the gripper-u and applied to a receiver. This receiver may be in the form of a carrier, preferably one at each side of the machine, which takes the transverse filaments from the grippers and carries them in a direction longitudinally ;of the machine for delivery upon the fabric to be reinforced.

It is desirable that the carriers should be provided with means for effectively holding the transverse, filaments as they are thus conducted longitudinally of the machine, and an important "feature of the invention relates to electric means for holding the filaments as they are conducted in this mannor by the carriers. 1

In accordance with the machine shown in said prior applicatiomithe filaments are con ducted from a source of supply at one side of the machine tothe grippers and are then distended by the'latter transversely of the machine. It is therefore desirable to sever a the transverse threads from their supply PAPER-REINFORCING MACHINE.

7 Referring to the dra\vin'gsz.' lhe ;ma1n frame of the machine maybe of any deslred character'suitablefor su-stannng the operating parts, and-may conveniently be of the.

form shown in'said' prior application;

The gri pers for-distending the filaments transverse y of .the machine'l'nay' be constructed the same as the grippers shown insaid prior application; and therefore need not be described in detz'iil hereinrbut it will mally under fao iss'

sufiice to say that the grippers on the grippercarrier at the supply side of the machine each comprises a fixed lower-"jaw member 1 which cooperates with an upper jaw member 3.n'or- A cam or. 1s mounted on a shaft 7 and IS tion of said shaft; as will be evident from Fig. 1.'

, .The grippers at the opposite or filament-- taking side of the machine also may be similar to the'taklng grippers shown in thesaid prior application and comprise upper and 1 lower jaw members-9 and 11 adapted to be opened bya spring 13 and clos'e'd by a rota.- tive cam 15; The grippers at the supply side of themachine are carried by brackets 17 depending from a truck'19 having rollers 21adapted to travelylongitudinally on a track. 23

416' from one another transversely-of the macarried by an I-beam'25. I I Thegrippe rs at the opposite side of the machine are similarly carried by. bracket 27 depending 'from'a truck-29 having rollers- 31 adapted to travel along a 'track- '33 carried by an I-beam' 35. These 'I-beams-,may be moved toward and chine to-cause the supply and taking grippers to approach" and recede from one anthe machine bya'mechanism similah to that Next will be deseribed the receiver for the filaments conducted transversely of themachine. As stated,.' this receiver may be in -the"form of a carrier. at each side ofthe machine, and since these earners are similar, a

description of one willsuffice for'both. The

carrier-comprises a sprocket chain 37, Fig. 3, supported by sprocket wheels such as 39- mounted on the shafts su'ch as ll journaled' in bearings, in aside frame 43: having a Korithe influence of a spring tend-' l ng to openthe jaw members. projection 5 adapted to .close said jaw members'on rotazontal top flange 45 for supporting the upper run of the sprocket chain and causmgthe same to travel in a rectilinear path.

The sprocket chain comprises a series of links, each of which may be provided with devices for receiving and holding the filam'ents delivered thereto from the. grippers, and since these devicesare s1m1lar,a e-

seript-ion ofone will sutfice for all. Each of 4 these devices comprises an upward extenslon 47 (Figs. 4, 5 and 6) having a V-shaped grooveeli) which engages and travels along a guide 51,-I ig.1, to further contribute to the'positive guidance of the'upper run of the hain in a rectilinear path.' v

Extending upwardly from 'thisextension is a plate 53 having a series of teeth 55 projecting upward and offset laterally from the top edge thereof, Cooperating with these teeth are a series of'fingers 57 preferably of 'resilient material and secured to' a baclrbar ,59 "adapted to reciprocate in a recess in a block 61 mounted on the extension 47'- and projecting upwardly opposite the toothed plate'53. The spring fingers are adapted to reciprocate in-*this space toward and from the teeth 55 and said fingers and teeth cooperate as jaws to clamp the filamentsbetween them. 'To facilitate the entranceof .the; filaments .between them, said teeth may have pointed heads 63 and shoulders (55 adapted to overlie the upper ends of said fingers when the latter are in open position to insure guidance of the fila ments properly between the teeth and fin- 'gersq Preferably; the fingersare'inclined somewhat from 'the' vertical to the right,

Fig. '5 so that on movement toward the. teeth to grasp the filaments (between-them, the fingers willflextoa verticalpositi'on and thus be 't'ensioned and provide a desirable pressure which will insure-secure retention of the filaments.

To shift saidfsp'ring fingers to the left of Fig." 5, inreadiness to receive the filaments, the bar 59 maybe providedwith an L-shaped arm 67, Fig. 7, connected by a'helical spring 69 .with a pin 71 fixed on the block '61 reifer-red-to.

To shift said fingers to the right, to grasp the filaments between said teeth and fingers,z-iuitable electrica means may be provided typified herein in tne'form of a solenoid 73 mountedon theblock 61 and h av-. mg a core'75 connected to thebar actuating arm 67. When. the solenoid. is energized, .it will draw its core to the right; Figs. 4'and 7, and thereby shift the fin 'er' bar 59 to-.

' vard the right andcause the ngers; to press the .filaments against the teeth 55. When the :core. is deenergized; the spring- 69 will 'be efi'ectiveto shift said 'ba'r in the opposite direction and mov'e the fingers to their .posi- I; tion shownin Fig. 4",]wherethey are in I readiness to permit the introduction of the trarisverse filaments between said fingers and teet Next will be described means for automatlcally energizing the solenoids at the proper times in the cycle of operations of the machine to grasp the filaments on the r of machines of this class, the filaments are carrier as they are the grippers.

presented thereto by It Will be understood that in the operation first distended transversely of the machine; thenloweredtoward the carrier ;then moved longitudinally of the machine a certain distance with. the carrier; then the filaments are grasped by the carrier; then they are released from said grippers and conducted longitudinally of the machine to the fabric to be reinforced.

After the grippers have delivered the filaments to the carrier, they areretracted longitudinally of the machine and in the course of this movement they may be moved toward one another transversely of the machine to bring the takin grippers into the positions where'they w1l be in readiness again to receive the filaments from the grippers at the supply side of the machine. While the grippers are retreating, the carrier is advanced longitudinally of the machine so' that the holding devices on the carrier supplied with the transverse threads are conducted forward and a set of empty holding devices on the carrier are brought Within range of the grippers in readiness to receive the transverse filaments therefrom.

Therefore, the holding devices approaching the range of the grippers should be deenergized and open in readiness'to receive the filaments, whereas the set of holding devices which have-just passed within the from by insulation pieces 79. A battery 81 or'other suitable source of electricity may be connected to a conductor 83 which may be grounded at the point 85 on the frame 45. The other side of the battery may be connected by a conductor 87 with a branch conductor 89 connected in turn to a brush 91 coiiperating with a conducting hub 93 of a commutator 95. The hub 93 may be connected by a conductor 97 with a segment 99 of saidcommutator having ends terminat ing with a substantial space of interruption 101 between them. A contact or brush 103 is adapted to engage with sa d contact segment on rotation of the" commutator and make or break the circuit according to whether or not said brush is in engagement with said contact segment or is opposlte the interruption between the ends of said seg ment. The contact 103 may be-connected by a conductor 105 with the contact rail 77 referred-to.

The commutator may be connected with any convenient rotating element of the machine, but should be caused to turn one complete rotation for each complete cycle of movement of the grippers, that is, the commutator should make one complete rotation each time the grippers are separated transversely of the machine, lowered, moved longitudinally of the machine, retreated and caused to approach. The rotation of the commutatoralso should be so timed that the circuit to the contact rail will be completed while a holding device is traveling the length of said rail.

To conduct the current to the coil of the solenoid one of said coils may be connected to a contact shoe 107, Fig. 3, adapted to slide along thecontact rail 77 and theother end of said coil may be connected to a contact shoe 81 adapted to slide along the top of the frame 45. Thus, when a holding de-' vice in the course of its orbit on the carrier reaches the contact rail, its contact shoe 107 will contact therewith and the circuit will be completed to the coil, thereby energizing the solenoid and shifting-the bar 59 and fingers 57 to the right of Figs. 5 and 6, and caus- 1 a ing the fingers to press the filamentsagainst the teeth 55 and securely hold the same.

In the present embodiment of the invention, the Contact rail .77 has been shown of a length suflicient to energize simultaneously six holding devices, but obviously the length of this rail may be varied to energize any number of holdlng devices desirable.

The energization of these devices should continue until they haveh'ad anopportunity to conduct the filaments to the fabric to be reinforced. Accordingly,. it is found convenient to provide a second contact rail 109, Fig. 3, whlch will continue the energ zatlon of the holding devices for a period after they have left the first rail referred-to. The

rail 109 may be also mounted upon the frame 45. and be supported therefrom .by lIlSlllEt'. tion pieces 111. This rail may be connected to the conductor 87 leading from the battery by a conductor 113. The conductor 113 will not be affected by the rotation of the commutator, and consequently, current from the battery will continuously stand on the frame 45 and rail 109, and thus,'when the holding devices come into contact with said rail and frame, their solenoids will be energized.

The rails 77 and 109 do not meet, but

have a'space between them .to permit the independent. electrical control of said rails.

Current is supplied tothe rail 77 intermit 5 sothat they will bridge the spac'e betweenthe contact rails. and engage the rail'109 before leaving the rail 77. Thus, the de-' vices after being energized in their transit over the rail 77 continue to -be energized for a period after leavingsaid rail determined by the length of the rail 109. It will be understood that a'series of filaments are lowered simultaneously by thegrippers to a set of the holding. devices and 15 consequently, it is desirablethat these holding device should be simultaneously en'er-- glzed in order to cause the grippers simultaneously to grip the series of filaments. The rotation of the commutator is so timed that all of these holding devices 57, will be simultaneously energized. The current will be'maintained on said rail until the lastof the devices thus energized will'have anopg portunity to leave said rail. As the leading holding device is passing from the rail 77, another holding device will-pass onto said rail and of course immediately on its arrival, will be energized', but it will be ineffective to hold any filament. All of the holding 30 rail, and after being energized thereby will bedeenergized by theinterruption in the commutator sothat the holding devices will be open a suflicient interval to allow a following set of filaments to belowered between their "clamping jaws.

Thus, the holding devices as they progress in their order, will successively become efi'ective to receive, hold, and conduct the transverse. filaments to the fabric to be reinforced. As stated, the filaments should be severed from their source of supply after being conducted transversely of'the machine in order' that the grippers may be eifective to distend a following set of filaments transversely of the machine. Next will be described a simple andeifective cutting mechanism for severing \the filaments from their supply after they have been transferred from the grippers to the holding devices and after the clamp thetransverse filaments to'the carrier. Referring more particularly to Figs. 1, ,2, 9 and 10: the form or cutting mechanism employed herein'to illustrate the invention, fcomprises ,the cutter 115 which may have a rounded or bluntcu'tting edge 117 adapted 'tof-coiiperate with a ledge or anvil 119, Fig. 5, on the top of theblock 61','referred-to, adjacent thefilament-holding teeth 55. A cutter 115 is provided for each ofthe holding devices, and'is secured to a horizontal bar 121 by screws 123 entering through verti- However, the con-' devices on the rail thus follow along on the holding devices have been energized to their elevated positions,

cal elongated slots 125 on said cutter. This will permit the cutter to automatically ad justand seat itself throughout the entire length of the anvil, and insure its engagement with all of the filaments on said anvil.

- The cutter-supporting bar 121 may be carried by the arms 127 fast on the-shaft 129 adapted to rock in bearings 131 depending --from a bracket 132 and secured to the truck 19 at the filament supply side of the machine. 7

' When the supply and taking grippers have approached transversely of, the machine, the cutter should be elevated so as to 'be out ofthe way of said grippers, as.

will' be seen from Fig. 2. Toelevate" the cutter, the truck carrying the taking grippers may be provided with an arm 133 having anupturned end with a screw 135 tapped therein, and adapted to be held by a lock nut in different positions of adjustment. This .screw is adapted to engage anarm 1337 projecting upward from and fast on'the cuttercarrylng rock shaft 129. By this mech-- I anism, it will be apparent that as the grippers approach one anot er, the screw on the. arm 133 will engage the arm 137 and rock meeting of said grippers.

the cutters upward shortly prior to the The cutters. should. be lowered to sever.

the filaments after the grippers have moved away from one another transversely of the machine, and to accomplish this, each cutter may be provided with a hammer 139 having a stem 141 adaptedto reciprocatevertically in a boss 143 projecting laterally fromthe bracket'132. The hammer is urged downward by a helical spring 145 confined be tween the head of the hammer and thelower edge of said bracket.

These hammers are so disposed with respect to the cutters that on the'elevatlon of the latter as described,'they w1ll engage the heads of the hammers and thrust their stems upward in said bosses. To hold the hammers cooked in their upward positlons, a hor1- 'zontal lock bar' 147 may be provided, Figs.

9 and 10, resting upon and adapted to slide along the tops of said bosses. a ser1es of key-hole slots 149 therein through which the stems of the hammers project. In order to lock the stems in their'upward positions, the small ends 151 of the slots are adapted to grooves 153 in the hammer stems;

The lock bar should be shifted to the left of Figs. 9 and 10, to lock the hammers 1n ed to the right of said figure to release said hammers. As stated, the bracket'132 supporting the lock bar per supporting true at the supply. side of the machine. .The movement ofthe truck This bar has slide into the' circumferential 12 0 and should be shiftis carried by the. gripforward and back longitudinally of the machine may be utilized to automatically move said bar to its hammer-locking and releasing positions. To accomplish this, there may be provided a stop arm 155 fast on the ma chine at a point adjacent the rearward limit of travel of-the truck. An adjusting screw 157 in the free end ofthis arm is adapted to engage an upstanding end 159 of said lock bar when the latter is carried. by the truck to a point somewhat short of the rearward limit of travel of the truck. As the truck completes its rearward limit of travel, the hammer stems are moved rearward into the small ends 151 of the key-hole slots and thus are locked in their elevated position.

To release the hammers, an arm 161 is provided fast on the machine at a point adjacent the forward limit of travel of the truck, and has an adjustable screw 163 adapted to engage an upstanding end 165 on said lock bar. As a result, as the truck apt on.

By this invention, simple and effective.

means is provided for positively transferring the filaments from the grippers to the material to be reinforced; and means for severing the transversely conducted filaments from their source of supply with certainty and precision.
